dc.description.abstractPure cultures of pseudomonas putida, Nocardia sp., Bacillus circulans and a mixed culture, isolated from mangrove forest soil, were used to study phenol biodegradation in the batch reactor. The aim was to determine the kinetics of phenol biodegradation by measuring the biomass growth rates and phenol concentration as a function of time in a batch reactor. The kinetic constants, specific growth rate ( m), inhibition coefficient for phenol (Ki) and half saturation coefficient for phenol (Ks) were determined using the Haldene equation [ ms/(Ks + S + (S2/Ki)]. The values obtained for kinetic constants are in the range of those published in literature for pure and mixed cultures degrading phenol. The length of the lag phase before the exponential growth phase increases linearly with phenol concentration. As compared to others, p. putida has the maximum specific growth rate both in the present study as well as in literature. Thus, selecting a pure culture of p. putida for phenol degradation could lead to higher efficiencies.en_US
